MTED STATES PATENT JOHN C. DRESSEL, OF FRESNO, CALIFORNIA.

SPEGIFICATIQN forming part Of Letters Patent NO. 64'7,8l6, dated April 1'7, 1900. Application filed September 21, I896. Serial No. 606,519. (No model.)

To all whom it may concern.-

Be it known that I, JOHN CHRISTOPHER DRESSEL, a citizen of the United States, residing at Fresno, in the county of Fresno, State of California, have invented a new and useful Sheet-Metal-Moldin g and Sheet-Metal- Ornamentin g Machine, of which the following is a specification.

My invention relates to the improvements in curved sheet-metal-molding and sheetmetal-ornamenting machines, in which a dieholder is adjustable upon a bed-plate independently, so that the coincidence of the die upon the die-holder with the die of the hammer-arm may always be assured; and the objects of my improvement are, first, to make it adjustable in all its working parts; second, to afford facilities for the proper adjustment of the dies independently of each otherin respect to the dies of the hammer and die- .holder, and, third, to provide for an adjustdie-holder on the line 1 2; Fig. 5, a top view 4 of the cross holding the die-holder and bed-- plate in proper relation to each other.

Similar letters and figures refer to similar parts throughout the several views.

The block A, block B, and block 0, and the standards D D constitute the framework of the machine. Block B is secured to block A by means of wedges a a. Block O is held in position by the rods and turnbuckles b b. The hammer-arm E is secured to block 0 and works on the pin 0. To the hammer-arm E are attached the movable weight 01, the adj ustable screw e, and the spring f, as referred to hereinafter, and also the adjustable leverrod and turnbuckle g g, as hereinafter set forth, and die 72, attached to the end of the hammer-arm E. The foot-lever F is attached to block 0 by means of a hinge 2'. To the foot-lever F is bolted the adjustable plate H, as hereinafter set forth. The die-holder I is That portion of Fig. 3 above the dotted line l 2 constitutes the die-holder I, and that portion below the dotted line 1 2 constitutes the bed-plate J. The dies are seen red in the dieholder I by means of bolts 4 4 4 4 and provided with lock-nuts. The die-holder I and the bed-plate J are secured to each other by cross 5. (Indicated in Figs.4 and 5.) The cross 5, Fig. 4, is secured to the bed-plate J by bolts 7 7 and to the die-holder-I by bolts 8 S in Fig. 4, lugs K K of Figs. 3 and 4 being a part of bed-plate J, and L being a part of die-holder I.

The die-holder I is adjustable to the bedplate J in any directionby means of the bolts and lock-nuts 6 6 6 6 6 6 6 6, Figs. 3 and 4, as referred to hereinafter. The guide G is attached to the block B by means of bolts jj.

To the guide G is attached the gages M M, which are adjustable by means of the thumbscrews in 7.1, which form a guide to hold the sheet metal during operation. The die-holder I is adjustable upon the bed-plate J independently by means of the cross 5, Fig. 5, so that the coincidence of the die upon the dieholder I with the die h of the hammer-arm E may always be assured. I prefer to carry out this feature of my invention in the manner shown in Figs. 3 and 4, where it will be seen that four bolts, with their proper locknuts, rise vertically from the under side of the bed-plate J, through which they pass. A most accurate adjustment of the die-holder can be effected by the manipulation of these bolts and lock-nuts.

The weight dis secured to the hammer-arm E and adjustable, so as to increase or lessen the operating force. The rod and turnbuckle g g are adjustable upon the hammer-arm E and also on the foot-lever F by means of the bolt passing through the plate H.

I am aware that prior to my invention sheetmetal-molding machines have been made with male dies operating in conjunction with female dies. I therefore do not claim such a combination broadly.

What I do claim as my invention, and desire to secure by Letters Patent, is-- 1. The combination in a, machine of the character described, of a bed-plate, a crossplate or frame pivoted upon said plate to rock .in a vertical plane inone direction, and a die-holder pivotally supported upon the crossplate and adapted to rock tr'ansverselythereto in a vertical plane, substantially as described.

.2. In a machine of the character described,

the combination with the weighted'oscillating. hammer-arm, 0f the rod adjustable on said arm and being itself adjustable as to.

length, the foot-lever, and adjustable veonnections betweenv said lever and the lower endof the said rod, substantially as described.

3. In a machine of the characterdescribed,

the combination with the weighted oscillating hammer -arm, of the rod 9 adjustable thereon and provided with a turn-buckle, the foot-lever, a perforated plate secured to the foot-lever and adapted to receive the lower end of said rod adjustably, and a spring connecting the weighted end of the hammer-arm with the main frame,substantiall v as de scribed.- I

- 4. The combination in amachine' of the character described, of abed-plate, a universally-adjustable die-holder mounted on said plate,an oscillating hammer and an arm therefor,- and an'operating-rod adjustable on the arm and being itself adjustable as tolength, substantially as described.

5; In amachine of the character described,

the combination of the bed-plate, a die-holder, and a cross and fastening=screws ad j ustably uniting said holder with said bed-plate, substantially as described. I I t 6. In a machine of the character described, the combination of the bed-plate provided with oppositely-disposed raised lugs, a die holder mounted above the bed-plate and having depending lugs at right angles to the lugs on the said plate, a cross-shaped plate confined within or arranged between the lugs, and screws passing through the'lugs and entering the ends "of the members of the crossplate, substantiall y as described.
